   I'm running a script that lists subject and author upon hitting the

   the rn world?

If I understand your question, it's a major reason I left rn behind in
favor of GNUS:

(setq gnus-Select-group-hook
      '(lambda ()
	 ;; First of all, sort by date.
	 (gnus-sort-headers
	  '(lambda (a b)
	     (gnus-date-lessp (gnus-header-date a)
			      (gnus-header-date b))))
	 ;; Then sort by subject string ignoring `Re:'.
	 ;; If case-fold-search is non-nil, case of letters is ignored.
	 (gnus-sort-headers
	  '(lambda (a b)
	     (gnus-string-lessp
	      (gnus-simplify-subject (gnus-header-subject a) 're)
	      (gnus-simplify-subject (gnus-header-subject b) 're)
	      )))))

This nicely groups discussion threads together in a useful order.
Sorry, I don't know of an easy way to accomplish it with rn macros.
